This research was conducted at Research Farm of Isfahan University of Technology to examine the relations among phonologic, morphologic and physiologic traits and their effects on grain yield of 20 oat (Avena sativa L.) genotypes. A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3, and 130±3 mm evaporation from class A ...
The assessment of crop water productivity (CWP) is practical significance for improving regional agricultural use efficiency and conservation levels. remote sensing method a common estimating large scale CWP, the errors in CWP by originate mainly from inversion yield evapotranspiration (ET). phenological period important factor ET estimation. coefficient (Kc) harvest index (HI), which are close...
Water limitation is a major yield limiting factor in groundnut and transpiration efficiency (TE) is considered the main target for improvement, but TE being difficult to measure it has mostly been screened with surrogates. The paper re-explore the contribution of TE to grain yield in peanut by using a novel experimental approach in which TE is measured gravimetrically throughout the crop life c...
This study was conducted in Research Farm of Isfahan University of Technology to evaluate some of the agronomic and physiological traits and grain yield potentials of ten bread wheat cultivars using a split plot design with three replications. Main and sub plot consisted of optimum and stress moisture treatments (irrigation after 70±3 and 130±3 mm evaporation from class A pan) and wheat cultiva...
Background: Mungbean [Vigna radiata (L.) Wilczek] is known as one of the important crop Vigna group. In order to determine morphological traits mungbean, multivariate analysis will provide advantages in selection phase future breeding programs. Multivariate statistical was used and classify these traits. analysis, that includes principal component (PCA) cluster (CA), considered best tool for se...
The expansion of the world's population requires the development of high production agriculture. For this purpose, it is essential to identify target points conditioning crop responsiveness to predicted [CO2]. The aim of this study was to determine the relevance of ear sink strength in leaf protein and metabolomic profiles and its implications in photosynthetic activity and yield of durum wheat...
Climate change and essentiality of the food security have motived scientists to try innovative approaches, among which, crop growth models can help to predict crop yield. In order to simulate tomato (Solanum lycopersicum) growth, phenological characteristics of a short-life variety of tomato were assessed. Phenologic characteristics included leaf area index (LAI), specific leaf area (S...
Soil compaction has become a widespread problem in the world and is one of the factors involved in land degradation and declining crop yields, especially in the arid and semi-arid agriculture. The purpose of this study was to investigate the effects of subsoil compaction on morphological, physiological and agronomic aspects of wheat .The research was carried out in the experimental farms of Anb...
In order to evaluate the growth indices and effective morphological and physiological traits of spring wheat (Triticum aestivum L.) using the multivariate statistical method, an experiment was conducted on the basis of randomized complete block design with three replications in Meshkin Shahr, Ardabil province in 2007. During and at the end of the growth season some physiological and morphologic...
